Table 2. The Calculated and Measured Molecular weight of the Synthesized [(diethylene glycol)adipate]diol

	MW (g/mol)	Reactant ratio EquAA/EquDEG
1Calculated Mn using Carothers Eq.	330.7	0.5
2Determined Mn using the measured hydroxy value	374.7	30.55

The molecular weights were calculated using Carothers equation, M ¯ N = ( D P ¯ N × M ¯ O ) + M ¯ O , DP_N = (1+r)/(1+r−2rp) with the value of Mo=108, Mc=18, and p=0.982. The conversion was measured from the acid value of the reactant-product mixture.
The molecular weights were determined using the measured hydroxy value (OH value) of the [(diethylene glycol)adipate]diol.
The reactant ratio was estimated using Carothers equation with the Mn (374.7 g/mol) determined from the hydroxy value.
